Īsumā par pleca artroskopiju
Dr Masaki Watanabe began to modify arthroscopic equipment in the 1950’s - Development during subsequent decades produced smaller diameter arthroscopes, higher quality lenses, fibre-optic light sources and the charge coupled device (CCD) camera

The shoulder complex consists of the glenohumeral, acromioclavicular, and sternoclavicular joints, along with the scapulothoracic articulation.

Key points
The rotator cuff is composed of four muscles: supraspinatus, infraspinatus, teres minor, and subscapularis. The muscles serve to rotate the arm and stabilize the humeral head
Rotator cuff injuries encompass a spectrum of conditions that affect the muscles, tendons, and bursa around the glenohumeral joint. Injuries include tendinitis, tendinosis, impingement, and tears
Tears are stratified by full or partial thickness, and by acute (>3 months) or chronic presentation. In young patients, tears are usually from acute injuries. Most older patients with rotator cuff tears are relatively asymptomatic
Suspicion of rotator cuff injury should be high if the patient cannot actively abduct or raise the arm or can only do so with significant pain
Consider magnetic resonance imaging (MRI) to rule out a tear in symptomatic patients with acute injury in preparation for early surgical intervention, particularly patients who require full shoulder mobility for employment
Otherwise, conservative treatment with rest, physiotherapy, nonsteroidal anti-inflammatory drugs (NSAIDs), and corticosteroid injections is first-line therapy. Conservative treatment may restore range of motion and strength, and eliminate pain even in patients with rotator cuff tears
The Neer impingement sign is helpful to evaluate the shoulder for impingement or rotator cuff tear. Place one hand on the posterior aspect of the scapula to maintain it in the anatomic position and use your other hand to take the patient's internally rotated arm by the wrist and place it in full flexion. This maneuver compresses the greater tuberosity against the anterior acromion and elicits discomfort in patients who have a rotator cuff tear or rotator cuff tendinitis
The Hawkins impingement sign reinforces a positive Neer impingement sign. Flex the patient's shoulder to 90°, flex the elbow to 90°, and place the forearm in neutral rotation. Support the elbow and then internally rotate the humerus. Pain elicited with this test is indicative of rotator cuff tear or rotator cuff tendinitis
Patients with a frozen shoulder will have severe restrictions to both passive and active motion, indicating adhesive capsulitis or calcific tendinitis
Deep-seated pain reproduced by passive motion and joint palpation should raise suspicion of glenohumeral osteoarthritis

Orthopaedic tests for bicipital tendinosis:
Speed's test: With the patient's elbow completely extended, supinated, and the shoulder flexed forward at 45 degrees, the practitioner palpates the biciptal groove with one hand while resisting active elevation of the patients same arm with the other. Pain within the proximal bicipital grove represents a positive.
Yergason's test: This test evaluates the integrity of the transverse humeral ligament. With the patient seated and the elbow flexed at 90 degrees, stabilise the patient's elbow with one hand whilst holding the patient's wrist with the other. Instruct the patient to externally rotate the shoulder, flex the elbow and supinate the wrist whilst resisting this movement. A snapping sound and or pain within the bicipital grove indicate a positive test.

INDICATIONS FOR SURGERY IN ANTERIOR SHOULDER INSTABILITY
Surgery is recommended in a shoulder that has persistent instability and pain despite an adequate period of rest, rehabilitation, and attempted return to full activity. Rarely, surgery may be recommended after a first time dislocation in certain high risk individuals (military, contact athletes, severe labral tearing on MRI scan). It is more common for a surgeon to recommend rehabilitation in most cases. The risk of recurrent instability in young patients (teens/twenties) after a 1st time dislocation is greater than 50%. If a second or third dislocation occurs, it is advisable to have shoulder stabilization surgery to minimize the risk of further damage to the shoulder labrum and bone. In cases of labral tearing without frank dislocation, the exact indications for surgery are less clear. Simply put, if the shoulder has failed 3-6 months of nonoperative treatment and remains painful and unstable with activity, surgery is probably warranted.
ARTHROSCOPIC SHOULDER STABILIZATION SURGERY
When the patient and physician have agreed that shoulder stabilization surgery is needed and warranted, the surgery is usually performed arthroscopically in the outpatient setting. An interscalene block (regional anesthesia) with or without general anesthesia is performed. Surgery is performed utilizing 3-4 small incisions with the help of the arthroscope. During the surgery, the labrum is visualized and freed from scar so that it can be mobilized into its normal anatomic position. Bioabsorbable suture anchors are then inserted into the glenoid bone; these anchors each have a suture that is used to reattach the labrum back to the bone. Three to four anchors are usually required to reattach labrum to bone in the setting of recurrent anterior dislocation. A sling and cold therapy device are placed in the operating room to use postoperatively. The following figures depict a typical arthroscopic anterior stabilization and labral repair.

Sufficient methods have been developed for treating small fractures. Dealing with them is an integrated part in suture anchor refixation of the labrum. 11 In cases of recent fracture, the refixation of the capsulolabral bone unit is performed. In old fractures, resection of the fragment is favored, despite possible risk of chronic instability due to the loss of glenoid support.
Adhesive capsulitis (AC) is a common disease that affects 3 to 5% of the general population, is more prevalent in females than in males (2:1), has an age of onset from 40 to 60 years of age, and causes pain and limitation in shoulder range of motion
